I would recommend that you talk with an attorney about the ramifications of incorporation and which corporate form you should choose. S corp vs C corp vs LLC vs Partnership.

Part of the consideration is your legal liability and how your profits will be taxed. If you incorp, you will need to pay yourself ( and payroll taxes), and file a seperate tax return. C corps get taxed once at the corp level, then again on your personal taxes.

There are a lot of good resources on the web that can help you understand the core issues before talking to the lawyer.
